1 II. Kinds of Chemical Bonds (p.304-308) Ch Chemical BondsII. Kinds of Chemical Bonds (p )Ionic BondCovalent BondComparison Chart
2 A. Ionic Bond Attraction between 2 oppositely charged ions Ions - charged atomsformed by transferring e- from a metal to a nonmetal
3 A. Ionic Bondions form a 3-D crystal latticeNaCl
4 B. Covalent Bond Attraction between neutral atoms formed by sharing e- between two nonmetals
5 B. Covalent Bondcovalent bonds result in discrete moleculesNH3H2OCl2
6 B. Covalent Bond Nonpolar Covalent Bond e- are shared equally usually identical atoms
7 + - B. Covalent Bond Polar Covalent Bond e- are shared unequally between 2 different atomsresults in partial opposite charges+-
